I travel almost every week and am always very careful to put my ecig away and not vape around the help. As an ex smoker I am absolutely horrified at the smell of tobacco smoke can't stand to be within a mile of it. I guess you could say I'm pretty extreme about it - I won't linger in an area with a smoker and I won't stay in a room that has even the faintest whiff of smoke. It completely disgusts me. So I am a little more sympathetic to Marriott trying to cater to their vast majority of customers. They just need to be educated - a lot of companies are just finding out about ecigs. Smoke detectors, by the way, aren't bothered by ecigs in general unless you blast a vape right into them. I've vaped in a dozen hotels and cruise ships and never had a problem but I keep it to myself.
